why different behaviour between ipa and running directly on device - ios

Exception Type: EXC_BAD_ACCESS (SIGSEGV)

when error like this happens when using ipa, but not run on simulator or directory on device,

when error like this happens when using ipa, but not run on simulator or directory on device, the reason mostly likely is the different optimization level between debug and release

Flutter app crash with debug build in TestFlight

We are developing a flutter application and are trying to test it via TestFlight. It uses amplify. If we submit a release build, it works well and can be tested. If we submit a debug build it crashes on start. By debug build I mean that in Product -> Scheme -> Edit Scheme -> Archive -> Build Configuration is Debug.
When debugging on simulator or a device via VSCode if Start Debugging is selected and under Breakpoints All Exceptions is selected, the app crashes with PlatformException:
PlatformException (PlatformException(SignedOutException, Translating
platform exception failed. Please take a look at
https://github.com/aws-amplify/amplify-flutter/issues to see if there
are any existing issues that match your scenario, and file an issue
with the details of the bug if there isn't., {recoverySuggestion:
Please sign in and reattempt the operation., message: You are
currently signed out.}, null))
If the option All Exceptions is not selected, this doesn't get triggered and the app runs successfully. This may not be connected at all, but is the only place, where the app seems like it's crashing when running it.
This is from the crash report on the iPhone:

App crash on launch Apple reject

I have test and submit my app to Apple Store but Apple reject and response my app crash on launch. I have test my app on many model iPhone and iPad it's working normal, Have anyone can tell me why?

Now i can't test with iOS 11.2.5 because Apple not allow signing in iOS version 11.2.5 or downgrade version to 11.2.5. Please help me.
Collection was mutated while being enumerated.
This mean that you have some data structure (like dictionary or array) and you iterate over elements and in same moment modify this structure, for example remove some elements. I suppose you to check all iteration that you do on very start. Or use symbolic breakpoint to find it. Note, that such crash can be a little bit tricky, because i guess some operation like remove or so may be not performed. Because of this you may or may not have crash on start
I solved mine by doing the following,
1. Symbolicate the error logs received from Apple.
2. Delete the app completely from you actual device and run a build from Xcode on it, this time it will crash and show you the lines where the bugs are!!!

iOS app crashes with EXC_CRASH (SIGKILL) when launched via TestFlight, but runs fine from Xcode

I'm running into a strange issue whereby an app I'm building crashes shortly after launching as an archived build from TestFlight, but runs without issue when running on the same device directly from Xcode. The application doesn't appear to be terminating fully - if I double-tap the home button, I see what looks like an image of the application in the background from midway through a run, even though the new session crashed long before it would have gotten to the displayed screen. If I then bring the application back to the foreground, it returns to its loading screen and then shuts down again, with a log that looks like this:

...Any thoughts on what I should be investigating to understand what's going on here?
App is built in C++ using the Cocos2d-x framework.
Thanks!

Figured out what was going on, if not yet exactly why. Some of the details posted above turned out to be red herrings as I investigated further. What initially appeared to be a difference in behavior between an archived build and a build launched directly from Xcode was actually a difference in behavior between a debug build and a release build.
The solution was to create a new scheme in Xcode to run a release build (Product->Scheme->Manage Schemes in Xcode 8.3), duplicate my default mobile scheme, and then set the new scheme's Run->Info->Build Configuration to Release.
Once I ran a release build with Xcode attached, I found an error (probably an incorrectly-initialized variable but I'm still investigating) that occurred in release builds only.
The reason why crash logs weren't being generated appears to have been that the error was causing an assertion to trip (the CC_ASSERT macro in Cocos2d-x), so iOS considered the app shutdown to be a legitimate termination and didn't log it as a crash.

how can I simulate EXC_RESOURCE exception on iOS Device

I would like to simulate Resource Limit [EXC_RESOURCE] Mach Exception on iOS.
Exception Type: EXC_RESOURCE
Exception Subtype: CPU_FATAL / WAKEUPS / MEMORY
Can someone help me write some bad code for testing that can help simulate some of these exceptions for my app on an iOS Device.

XCODE keeps crashing. Deals with auto layout

I clicked to turn off auto layout. And now I click the check box to turn it on, and xcode immediately crashes..Every time. I'm pretty sure that all tableviews have a datasource. I can't work on the project! Please help.

I just faced this problem and removing all of the File Owner's Outlets and Referencing Outlets did the trick.
Note: Firstly, as I couldn't turn off autoLayout graphically as Xcode crashed just by trying to view the .xib, I managed to do it following AbuYusuph's suggestion.
I was able to fix this issue by deleting the symlinks I had from the /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/ to the /Users/xxx/Library/Developer/Xcode/iOS DeviceSupport. I hope this will help.
I just remade an entire viewController and it works now. Not really answering the question. I am thinking it's just a glitch
